VTo ZE whom t muy concern:

lle it known that I, FLoRIAN A. KOMO- nowsnr, a citizen of the UnitedStates, re siding` llihnington, in the oountfy7 oi' New Castle und otDelaware, have invented .new und useful improvements in Rudio LoudSpeakers, oit which the following is u specific-ation.

This invention relates particularly tm empli` rnonly known es loudspeakers, und has for its object the provision of u novel device of thischaracter designed either for suspension from e ceiling; or othersupport or oonstrueted so lobe set upon s table or the like, the devicebeing formed for use in oonto radio apparatus .ng dev1ces coinl neotionwith on ordinary uni't such as a telephone unit of the ordinary 'varietyor ot' the sii-culled loud speelting variety.

The essentiel object of the invention is the provision of loud speakerwhich involves the use or o howl shaped reflector against which thesound waves are concentrated by ineens ont' :i conduit member at one endof which located the telephone unit, the bowl shaped member noting tomagnify the sound andthrow it in the desired direct-ion.

Another object is the provision of u do vice of this Character which isso constructed und arranged that it muy be used in either forni, thatis, the suspended forni. or the table torni, simple attachments beingprovided wherein.Y the conversion muy be inane from one to the other.

Another object the provision ot' u device of this chui-unter which nuxybe mede extremely ornunientul in appearance so as es to be veryattractive instead of unsightly es is the cose with the ordinary type ofloud speaker embodying u horn.

Still :mother ebd' et is the provision oi' o device of 'this characterwhich on account rol' its pecuiior construction will be moreadvantageous thun the ordinary horn type inasmuch us the tone. will beclearer und free troni the distortion which so often results t'i'ozn theuse of the wellhnown typen A u 'udditiiuml object ythe provision of sdevice of this @herunter which will be simple und ine pciiisiifc tomanufacture, eus i to in stell, positive in action, etloient and durablein use und u general improvement in the art.

lVith the above and other objeotsund advantages in View, the inventionconsists in the details of construction to be hereinafter more fullydescribed und claimed, and illustruted in the. uccon'lpunying drawingsin which:

Figure 1 is a side elevation of the device showing the tuble formthereof, the bowl member losing4 in section,

Figure 6 this forni.

Referring more particularly to the drow- .ings, the. numeral 10designates un elongated tubular conduit which has one end slightlyconstrioted as shown at 11 for suitable en gugement with u phone or loudspeaker unit indicated ut l2. The details of this nuit are not disclosedas theyrform no partol the present invention and us these devices ere onthe nmrketund well known. lt suffices to soy, that this unit is equippedwith wires 13 which ure adopted to be connected with the output from anyrudio set whereby to operate the unit. The otltei nl of this member l0is outwardly iured as indicated :it 14, and carriesn bell-like ineinber15 of suitable material which is here represented us secured in place byset screws 16 or the like. This member 15 is substantiully the saune asu globe used in connection with electric lights and in foot such a globemay actually be used if preferred.

Slidubly udjustably mounted upon the tubular conduit member 10 is ucollar 17 held in adjusted position by means of u set screw 18 or thelike and formedat one side with a threaded socket 19 for u purpose to`be described. The numeral 2() designates u 00 i is a longitudinalsection through snuped reflector or detiector which may be of metal,glass, china, orcelain or any other suitable material an of any desiredsize. This bowl shaped member may be ornamented on one or both sides, aspreferred, in order that the entire device will have a most pleasingappearance. Secured to the edge portions of the reflector or bowl 20 arerods or other brace elements 21 which converge and which are connectedwith the collar 17 as shown. Obviously, by loosening the set screw 18,the collar "i7 and the bowl member 2O may be adjusted with respect tothe member 15 so as to vary the space between the outlet or o en end otthe member 15 and the center ot tie bowl. This adjustment is necessaryin order to secure the best results and to project the sound mostefliciently in the desired direction so that proper amplification willbe had while therquality remains clear, loud and sweet.

As shown in Figures 5 and 6, the device is well adapted for suspensionfrom a ceiling or other overhead support and in carryM ing out thisfeature, I provide an attaching plate member 22 which may be screwed,nailed or otherwise fastened to a ceiling or other support and which isprovided with a suspension element 23 from which depend chains or otherflexible members, 24 connected at 25 with the bowl or reflector 20.

The device is equally capable el use mounted upon a table, shelf orother support, and ioi this reason I make use of a standard or post 26having a threaded end adapted to be screwed into the threaded socket 19which forms a part of the collar 17. At its lower end, the post orstandard 2G has a threaded extension 27 which is screwed into anupstaiiding fei'iule 28 mounted at the center of a suitable base 29which is preferably equipped with rubber feet 30 to Vavoid niariing thetop of the table or the like. lVheii the device is used in thehorizontal oi' table position as shown in Figure 3, it is necessary toprovide a counterbalancing weight 31 to compensate for and balance theweight ot the b'owl like reflector 20. This counterbalaneing weight 31is shown as equipped with a suspension ring 32 or the like engaged uponthe constrictcd vend, portion 11 of the member 10 as clearly shown inFigure 1.

In the use of the device it is quite appar ent that the sound waves willtravel i'roin the unit 12 through the tubular conduitmember 10 and willbe concentrated by the member 15 onto the center of the bowl orreflector 20, from which the sound waves will be reflected back in amagnified form so as to be clearly audible all overa room or otherplace. In actual practice I have discovered that the provision of thisbowl device gives the proper amplification 'without in any way causingany distortion of the soundand in this way the device acts 'far morecfliciently and satisfactorily than the well known type ot' loud speakereinl ploying a horn. Owing to the fewness of the parts and theadjustable features it is quite evident that the device is bound to actelicieiitly even under the most adverse circumstances so that goodresults will be obtained at all times.

While I have shown and described the preferred embodiment of theinvention, it should be understood that I reserve the right to make suchchanges in the form, con.-

`struction and arrangement of parts as will not depart from the spiritoit the invention or the scope of the subjoined claims.

Having thus described the invention, I claim:
